Finsix was founded in 2010 with plans to miniaturize the bulky chargers for all sorts of electronics. The laptop charger market was the first area in which the Finsix team thought it could make a worthwhile difference and in which it thought it could gain traction.
After four years of development, the team launched on Kickstarter to raise funds for production of the Dart charger on April 14th. The company reached its US$200,000 goal in just 12 hours and is well on its way to doubling that figure by the end of the campaign.
Finsix says that the Dart is, "the world’s smallest, lightest laptop adapter." It provides 65 W of power and works with inputs of 90-265 V, connecting via charger port or via USB for other devices. The charger takes up just 2.5 cubic inches (6.35 cubic cm) and it weighs 60 g (2.1 oz), with a 6 ft (1.8 m) power cable. According to the company, the Dart will work with most PC laptops and will work internationally. Dart for MacBook and Custom Dart models are also available.
Finsix says it has been able to reduce the size of the charger by increasing the speed of the switching cycle and minimizing the amount of energy lost. "Switching isn’t a perfect process and during every cycle some energy is wasted in the form of heat," the company explains. "At Finsix, our technology allows us to waste far less energy with each cycle. Thus, we can cycle up to 1000x faster without wasting any more energy than a conventional power converter. Cycling faster means we can transfer a smaller packet of energy to each cycle – and make the power converter a lot smaller."
Those wanting a Dart charger can make a pledge on Kickstarter, starting at $89. Alternatively, the device will be exhibited at CES 2015 in January, with commercially availability expected some time after that.
